We're dividing 54146 by 12 
We're looking to find how many times 12 goes into 54146.

Moving on to step 1:
5 divided by 12 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 12

On to step 2:
If we divide 54 by 12, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 54 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 12

Let's proceed to step 3:
61 divided by 12 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 60 from 61, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Advancing to step 4:
If we divide 14 by 12, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 451.0
If we take 12 away from 14, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Let's proceed to step 5:
12 goes into 26 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4512.0
Deduct 24 from 26 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 4512.1
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4512.16
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4512.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 4512.166 with a balance of 0.0008.
